A bag cleaning apparatus removes caked dust from the bags of a baghouse and prevents the removed dust from being recaptured. The outlets of each bag subject to cleaning and all adjacent bags are closed during the cleaning process and for a sufficient time following the cleaning process to assure that the dislodged cake falls into the lower hopper of the baghouse. Provisions are also made to clean portions of each bag more than others, where necessary, and to vary cleaning among the bags to optimize baghouse efficiency. A reverse air flow cleaning technique is preferably employed because it provides gentler cleaning than other known bag cleaning techniques and thus increases the life of the bags.
